Abstract

Abstract In the case of cartridge feed systems for automatic weapons or guns having an endless chain for feeding and storing the cartridges there is provided an outfeed mechanism for outfeeding the cartridges by means of the feed or conveying movement of the chain. In order to be able to store a number of different types of ammunition with such equipment and to be able to infeed such to the weapon or gun, the invention contemplates utilizing an outfeed mechanism wherein it is possible to selectively outfeed cartridges in both feed or conveying directions of the endless chain.
